Since it is under 985,000, you would round it down. So your answer rounded to the nearest ten thousand would be 980,000
The answer to your question is:
1/3x + 1/2x = x - 9
Ten thousand I believe let me know if wrong that’s what my math got
The first thing we are going to do for this case is to define the following variable:
x = number of trees.
We then have that the equation that represents the problem is given by:
y = 50 (x-1) + 20
Rewriting:
y = 50x - 50 + 20
y = 50x - 30
Substituting for y = 390 we have:
390 = 50x - 30
We clear x:
x = (390 + 30) / (50)
x = 8.4
nearest whole integer
x = 8
Answer:
will be planted along one block about 8 trees.
The slope is -1/2x in this case because it is always next to a variable y=mx+b.
